This is from a couple of days ago (ht Firehand): Regarding a report on the fact that 67 out of 70 times, TSA did not catch banned items during screening. Per the Homeland Security Talking Head, these reports don’t look good because they are taken out of context.
Uhmmm… the context was that they tested the system, and the system failed 95.7% of the time. There are times when there’s nuance–the scoring of gymnastics routines or ice skating, or my personal favorite, pole dancing. There are also times when there’s no nuance–simple tests–number of tests divided by number of finds. Which in this case is three. Three times out of seventy, the TSA found what they were supposed to. No nuance to the number three….
